WannaCry?

wannacry

The first and so far the only time I was personally involved, (or to be more precise my son who at that time was eleven years old), in a cyber-attack by ransomware was in 2012. The computer of my son was apparently blocked by the Federal Criminal Police Office due to some illegal actions, such as sending spam mails and even worse. At least that’s what appeared on the screen in poor German. Strangely enough a fee of 100 Euros would unblock the computer. Well, I wondered how the 100 Euros would affect  the illegal activities, my eleven year old boy had committed but you never know. Even though it was obvious that we didn’t get into trouble with the public authorities, my son was not amused by the fact that his computer was out of order.

Secured data transfer

In February this year, a team of researchers both from Google and CWI Institute in Amsterdam announced that they were able to generate two PDFs documents with different content that would hash into the same SHA-1 digest.

Usually, the first Advent is the day when the contemplative time starts. The 27th of November, the first Advent in 2016 was for many people in Germany in a particular way very calm. Round about one million DSL routers, mainly devices from Germany’s biggest telecommunications carrier, fell victim to hacker attacks. (more…)

The role communications play in transport and the custody of securities

ipsecDespite the potential symbiosis between transport in armored cars and Information and Communication Technologies (ICT), two factors have prevented both sectors from making the most of the opportunities available. The first has to do with the limited bandwidth cellular technologies offered up until recently; the second with the lack of integration and interoperability of existing services (GPS, video, communications, etc.). These two factors have helped perpetuate this problem, which is also present in public and private security forces.
